ISSUE FOCUS FEED & ADDITIVE MAGAZINE May 2022 33 Additional results from a trial performed at Southern Poultry (USA), confirmed the interest of micro-encapsulation of phycogenics with phytogenics. In this trial, 3 groups of birds were fed with 3 treatments: a negative control, a second treatment with antibiotics (BMD) and a third group with a combination of phytogenics and phycogenics. In parallel, all animals were placed on a re-used litter to create a mild N.E. challenge. Performance results at 14 days and then 42 days were well in line with previous experimentations and showed that the micro-encapsulation of phytogenics and phycogenics could provide similar or better performance compared to other treatments. MICRO-ENCAPSULATED PHYTOGENICS AND PHYCOGENICS AS A NEW STANDARD Since the market of plant extracts emerged 30 years ago, there is now enough evidence and knowledge to understand the effects of these products, as well as the parameters that guarantee the optimal efficacy and best impact on gut health. Nutritionists can now expect solutions based on transparent formulation, which includes well-known but also innovative molecules, from land or marine plants, protected by advanced technology for stable and consistent effect. This novel generation of plant-based additives represents a great opportunity for formulators and nutritionists to further invest in sustainable technologies, to better address challenges related to gut health and create more value for their customers.
